number of buckets to allocate in the database. If a bucket already contains an entry, further entries are stored in a singly-linked list degrading search performance. Maximum number is 100000, must be greater than 16. The debug heap uses 6263.

Maximum number of bytes the database can grow in size to. This value is only checked when new segments are allocated. The initial size of the database can be larger than this value

pfnHash

Pointer to a function called to provide a hash of the stack frame contents. Can be NULL, in which case RtlpTraceStandardHashFunction is used which simply sums the pointer values.

In kernel mode, the tag parameter specifies the tag passed to ExAllocatePoolWithTag. Also, the flags parameter can be given the value 4 to indicate segments are allocated from the Nonpaged pool. The initial allocation is always from the NonPaged pool
